The following illustration shows the cable routing for the configuration 3. Connections between connectors:
1 ↔ 1 , 2 ↔ 2 , 3 ↔ 3 , ... n ↔ n
Note: For models that support Gen 3 and Gen4 adapters at the same slot, the illustration shows only the
cable routing information for Gen 4 adapters, the routing and connector information is similar for Gen 3
adapters.
